Terpenoid
It's a great manga, but I get pissed at parents like this. You DO NOT put your life on hold for your child unless you want a clingy, spoiled "mama's boy" who will interfere in your life even after they become adults. You INCLUDE your child in your life. Be honest and open with them, don't hide trivial or important things. Even in a homosexual couple, children NEED to see two adults interacting in adult relationships in order to know how to handle them when they become adults. If you're cold to your partner or spouse in front of children, they will assume that that is the correct way to treat their partner or spouse in the future. Conversely, if you show your children that two adults can be warm, loving, supportive and caring, that is how they will treat their future partners. When an argument arises, don't hide it, but argue like adults. Even if there is a "blow up" of emotion, let them see. Then, let them see how you calm down and talk it through to arrive at a solution. This is how children, especially young children, learn... through example. No one "taught" me this. I learned by trial and error with three sons. Sons who love me and their dad immensely, come to us often for advice and treat their partners the same way they saw my husband and me treat each other... with love, warmth, kindness, respect and compassion.

The plot of the story was interesting, but the "love" connection between the protagonists felt tissue paper thin.
